While driving locally the indicator lights on the dashboard started flashing (cruise control, check engine and brake lights). Parked car, checked gas cap and disconnected battery and cleaned terminals, problem continued. Took the car to our local auto mechanic (after some not so pleasant dealings with Subaru) 7/22/19 he performed computer diagnostic and found faulty oxygen sensor. $601. 38. Car worked well until today. Returning home from store the lights are flashing again back to the mechanic. 18,000 miles on the car!.
